MdeModulePkg/Core/Pei: Install MigrateTempRamPpi
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4716
Migrate FSP-T/M binary from temporary RAM to permanent RAM before NEM
tear down. Tcg module will use permanent address of FSP-T/M for
measurement. In MdeModulePkg, PeiCore installs mMigrateTempRamPpi if
PcdMigrateTemporaryRamFirmwareVolumes is True before NEM tear down and
after permanent memory ready.
